I need to know if i should file a Miller Act Claim

Steel Standing was hired as a sub contractor to provide the labor for a job on Fort Jackson. I was hired as the second tier sub, not directly with the Prime contractor. Your Roofers, LLC who was contracted with the Prime Contractor turned in certified payroll to the prime contrator. However they never did pay the guys, my company paid the guys. Now i am told the prime contractor will not pay the contractor i am contracted with due to not fullfulling their contract. When i ask Your Roofers, LLC about submitted fake documents they indicated they are going to pay all the tax liability on the guys on the cerified payroll. However, bottom line, Steel Standing, LLC paid more than $ 120,000 for labor on this job and now can not get paid. There is no profit in that number either.
